Abstract

PROBLEM TO BE SOLVED: To automatically regulate the operating speed of a passenger conveyor to a proper value by a user by providing a passenger's weight detecting means near the platform of the passenger conveyor, and automatically regulating the operating speed on the basis of the output signal of the weight detecting means. SOLUTION: When no subject to detect is present in a weight detecting means 3 set near a platform, the magnitude of the output voltage V1 of a voltage converting circuit 4 is V1<VH, V1<VL, and an output is generated from a comparative circuit 6. Consequently, a speed switching signal is outputted from an output circuit 7 to operate a passenger conveyor at a general operating speed. On the other hand, when an adult user is detected, the output voltage V1 is V1>VH, V1>VL, and an output is generated from a comparative circuit 5 to operate the passenger conveyor similarly at the general operating speed. However, when a user such as a light child is detected, the passenger conveyor is switched to a prescribed speed since each comparative circuit 5, 6 generates no output.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will now be described with reference to FIGS.
This will be described with reference to FIG.

In FIG. 1, 1 is a passenger conveyor,
2 is a weight detecting means. The item 2 is installed at a position where the user always passes when the user gets on the item 1 and there is no detection leak.

FIG. 2 is a block diagram showing an automatic switching operation of the passenger conveyor according to one embodiment of the present invention.

In FIG. 2, reference numeral 3 denotes a weight detecting means corresponding to the above 2, and 3 generates an output linearly according to the weight. Reference numeral 4 denotes a voltage conversion circuit that linearly converts the voltage into the voltage V1 in accordance with the output of the above 3. In this embodiment, the smaller the weight of the user is, the smaller the voltage is generated. 5 compares the output voltage V1 of 4 with the reference voltage VH, and V1>
The comparison circuit 1 generates an output in the case of VH. Since the set value of VH is set to a value corresponding to a predetermined weight at which the driving speed is switched, if the user is above the predetermined weight, V1> VH and an output is generated. Reference numeral 6 denotes a comparison circuit 2 which compares the output voltage V1 with the reference voltage VL and generates an output when V1 <VL.

Since VL is set to a value corresponding to a weight that is clearly lighter than the weight of a human, V1 <VL is generated only when there is no user, and an output is generated. 7 is 5
AND of the outputs of the outputs VL <V1 <V
This is an output circuit that generates a signal for switching the operation speed of the passenger conveyor to a predetermined speed at the time of H.

The operation will be described with reference to FIGS. 1 and 2. If there is no user, there is no object to be detected, so that the magnitude of the output voltage V1 is V1 <VH, V
1 <VL. Accordingly, 6 produces an output. As a result, since the above 7 does not output the speed switching signal, the passenger conveyor operates at the normal operation speed.

When an adult user who is considered to be relatively heavy intends to use the passenger conveyor, the aforementioned 3 detects the weight, and in this case, the magnitude of the output voltage V1 of the above 4 is V1> VH. , V1> VL. Thus, said 5 produces an output. As a result, since the signal 7 does not output a signal relating to the switching of the operation speed of the passenger conveyor, the passenger conveyor operates normally.

On the other hand, when a relatively light person, such as a child, uses the light, the above 3 detects the weight, but since the weight is light, the magnitude of the output voltage V1 of the above 4 is V1 <VH,
V1> VL. Therefore, neither 5 nor 6 produces an output. As a result, the signal 7 outputs a signal for switching the operation speed of the passenger conveyor to a predetermined speed, and the operation speed of the passenger conveyor can be switched to the predetermined speed based on the signal.

FIG. 3 shows another embodiment of the present invention. In the case where there is no user, the vehicle stands by without driving, the vehicle is driven only when there is a user, and the driving speed depends on the weight of the user. FIG. 2 shows a block diagram of a passenger conveyor for adjusting the temperature.

In FIG. 3, reference numeral 8 denotes a weight detecting means corresponding to the above 2, and 8 generates a linear output in accordance with the weight value. Reference numeral 9 denotes a voltage conversion circuit that linearly converts the voltage into the voltage V1 in accordance with the output of the above 8. In this embodiment, the smaller the weight of the user is, the smaller the voltage is generated. 10
Compares the output voltage V1 of 9 with the reference voltage VL,
The comparison circuit 3 generates an output when> VL. V
Since L is set to a value corresponding to the weight that is clearly lighter than the weight of a human, V1> VL when any user is present regardless of the weight, and an output is generated. Reference numeral 11 denotes a comparison circuit 4 which compares the output voltage V1 with the reference voltage VH and generates an output when V1> VH. The set value of VH is
Since the driving speed is set to a value corresponding to the predetermined weight at which the driving speed is switched, if the user is at or above the predetermined weight, V1> VH, so that an output is generated. Reference numeral 12 denotes an EOR circuit that generates an exclusive OR from the outputs from the outputs 10 and 11, and reference numeral 13 denotes an output circuit 2 that generates a start signal for operating the passenger conveyor at a predetermined operation speed from the output of the output 12. Reference numeral 14 denotes an output circuit 3 for generating a start signal for operating the passenger conveyor at a normal operation speed from the output of the eleventh embodiment.

As shown in FIG. 3, when there is no user, there is no object to be detected, and the magnitude of the output voltage V1 becomes V1 <VH and V1 <VL. Therefore, both 10 and 11 do not produce an output. As a result, 13
And 14 do not output a signal regarding activation, so the passenger conveyor waits without activation.

When an adult passenger who is considered to be relatively heavy tries to use the passenger conveyor, the above-mentioned 8 detects the weight, and in this case, the magnitude of the output voltage V1 of the above 9 becomes V1> VH, V1> VL. Thus, both 10 and 11 produce an output. As a result, the 14 generates a start signal for operating the passenger conveyor at the normal operation speed, and the passenger conveyor starts operating at the normal operation speed.

When a relatively light person, such as a child, uses the light, the above 8 detects the weight, but since the weight is light,
The magnitude of the 9 output voltage V1 is V1 <VH, V1>
VL. Thus, only 10 produces an output. As a result, the 13 outputs a start signal for operating the passenger conveyor at a predetermined operation speed, and the passenger conveyor starts operating at a predetermined speed different from the normal operation speed.

According to the present invention, a means for detecting the weight of the user is provided near the landing of the passenger conveyor, and the operation speed of the passenger conveyor is manually controlled based on the output signal of the means for detecting the weight of the user. There is an effect that the adjustment can be performed automatically without any adjustment.
